【摘要】 针对网络化控制系统(Networked Control Systems,简称NCSs)运行中的基本特点,设计实现了一个NCSs的仿真平台,目的是为了模拟控制系统在网络环境下的操作及仿真过程,并对控制系统的理论分析与设计方法进行仿真检验。该平台采用VC++和Matlab混合编程的方式实现了三个基本功能,主要结构包括通信部分、控制系统仿真部分以及通信与系统仿真的接口部分等。针对VC++和Matlab不同环境下编程及交互的特点,文中对混合编程实现过程中的若干关键问题做了详细的分析并展示了结果。最后通过仿真实例来验证了仿真平台设计的有效性。更多还原

【Abstract】 This paper design and realize a simulation platform for NCSs focusing on the basic characteristics of networked control systems. The purpose of constructing simulation platform is to simulate the operating process of control systems under network, and to test the theoretic analysis and design methods for control systems. The platform is organized in VC ++ and Matlab, with communication part, control system simulation and the interface between communication and system simulation involved. Then, some key problem as well as programming realization under different program environment in VC + + and Matlab are discussed in detail. Last, the effectiveness of the simulation results is also checked by certain examples.更多还原
